Question

Write a program to perform the calculation of the following equation and save the result accordingly:

   f = 5x + 3y + z

Assumptions:

- Registers can be used to represent variables x, y, z, and f

- Initialize x, y, and z to values of your choice. f can be initialized to zero.

- Use comments to specify your register usage and explain your logic

Greetings!!

Code:

.data
x: .word 5
y: .word 3
z: .word 1
f: .word 0

.text

main:

lw $t0,x                                   #load x to t0

mul $t0,$t0,5                          #calculate 5x

lw $t1,y                                   #load y to t1

mul $t1,$t1,3                          #calculate 3y

add $t1,$t0,$t1                        #calculate 5x+3y

lw $t2,z                                   #load z to t2   

mul $t2,$t2,1                          #calculate z

add $t2,$t2,$t1                        #calculate 5x+3y+z

sw $t2,f                                   #store the result to f

addi $v0,$0,10                        #termination

syscall

Output screenshot:

For x=5,y=3 and z=1

f=35(or 23H)

Hope this helps
